Venice, which sits on a cluster of small islands separated by canals and linked by bridges, is experiencing higher than average water levels, reports Euro News. In St. Mark’s Square, tourists were seen donning makeshift booties as they navigated the narrow wooden platforms leading to the church.

In other parts of the city, knee-high water forced visitors to wade carefully through the streets.

Despite the high water, thousands of tourists are expected to visit the city during this festive season. This year, there will reportedly be more security throughout the city.

“This year Piazza San Marco will have a strict security and control,” Sergio Pomponio, city commissioner told the Venice Times.
